Hi Team,

In odoo16 timesheet module i have custom module timesheet based on approval so in table their is column approved_hours it should be based on users input but currently i am facing the issue and their one more column is there unapproved hours so these field should work like total hours is 40 and approved hours is 20 remaining 20 hours should reflect in unapproved hours 

please find the code of python

from odoo import models, fields, api, _

class TimesheetValidation(models.Model):
    _inherit = 'account.analytic.line'

    state = fields.Selection([
       ('draft', 'Draft'), ('submitted', 'Submitted'), ('approved', 'Approved'), ('rejected', 'Rejected'),('approved_hours','Approved_Hours'),('approved_by_customer', 'Approved_By_Customer'),('unapporved_hours',  'Unapproved_Hours')
       ], default='draft', string="States")

    status = fields.Selection([('draft','Draft'),
       ('reject', 'Reject'), ('approve', 'Approved')
       ], string="Status", required=True, default='draft')

    employee_id = fields.Many2one('hr.employee', string="Employee", required=True)
    approved_id = fields.Many2one('res.users', string='Approved By')
    rejected_id = fields.Many2one('res.users', string='Rejected By')
    approved_date = fields.Datetime('Approved Date')
    rejected_date = fields.Datetime('Rejected Date')
    rejected_reason = fields.Char('Rejected Reason')
    approved_hours = fields.Text('Approved Hours')
    approved_by_customer = fields.Text('Approved By Customer')
    unapproved_hours = fields.Text('Unapproved hours')

    @api.depends('unit_amount')
    def _compute_approved_hours(self):
       for record in self:
          record.approved_hours = record.hours

    @api.model
    def create(self, vals):
       vals['state'] = 'submitted'
       return super(TimesheetValidation, self).create(vals)




class TimeSheetValidationWizard(models.TransientModel):
    _name = 'timesheet.validation.wizard'

    reason = fields.Char('Rejected Reason')
    approved_id = fields.Many2one('res.users', string='Approved By')
    rejected_id = fields.Many2one('res.users', string='Rejected By')
    approved_date = fields.Datetime('Approved Date')
    rejected_date = fields.Datetime('Rejected Date')
    status = fields.Selection([('draft','Draft'),
       ('reject', 'Reject'), ('approve', 'Approved')
       ], string="Status", required=True, default='approve')


    def reject(self):
       active_id = self._context.get('active_id')
       current_record = self.env['account.analytic.line'].search([('id', '=', active_id)])
       
       current_record.status = 'reject'

       if current_record.status == 'reject':
          current_record.rejected_id = self.rejected_id
          current_record.rejected_reason = self.reason
          current_record.state = 'rejected'
          mail_template = self.env.ref('ak_timesheet_approval.timesheet_validation_email_template')
          mail_template.send_mail(current_record.id, force_send=True)

    def approve(self):
       active_id = self._context.get('active_id')
       current_record = self.env['account.analytic.line'].search([('id', '=', active_id)])
       current_record.status = 'approve'

       if current_record.status == 'approve':
          current_record.approved_id = self.approved_id
          current_record.state = 'approved'
          mail_template = self.env.ref('ak_timesheet_approval.timesheet_validation_email_template')
          mail_template.send_mail(current_record.id, force_send=True)
